Mofication
----------
Date:		20th April 2005
Author:		Paul Bilton & Oliver Southgate (Written by PB, added by OS)
Purpose:	With the existing date validation, it only checks for numeric 
			structure and does not account for number of days within the 
			month & Feb leap year day’s count.
Example:	<input type="text" id="txt1" value="" onblur="CheckDateFormatNew(this)">
